[目的]观察豆状囊尾蚴的头节在相对静止与运动时超微结构的变化。[方法]本研究用扫描电镜对位于囊泡内的头节和经人工培养后从囊泡内翻出头节的超微结构变化进行了比较观察。[结果]处于相对静止状态的头节从正面观察时，带有皮肌柱和齿钩的顶突呈伞状，覆盖于头节的前端。从侧面观察，齿钩具有鹿角样的分支，覆盖头节的齿钩仅有一排。4个吸盘呈洞穴状，位于顶突之后，均等地分布在头节的四周。当头节处于运动状态时，顶突上的皮肌柱收缩，鹿角样的齿钩向周围伸展，吸盘也发生环形和纵行收缩。[结论]豆状囊尾蚴的头节在相对静止与运动时的超微结构有明显的改变，这种变化有利于豆状囊尾蚴对宿主的侵袭。

[Objective] This study aimed to research the ultra-morphological changes of scolex of Cysticercus pisiformis during the relative rest and motion states. [Method] The ultrastructure changes of scolex located in cyst and evaginated from cyst after cultivation were comparatively observed by scanning electron microscope. [Result] When the scolex was in the relative rest state, observed from the top, the rostel um with the tegument muscular column that connected to tooth-hook looked like the umbrel a and covered on the front end of the scolex. Viewed from the side of the scolex, the tooth-hook on the rostel um looked like the antler branch and had only one row. Four suckers looked like cavities, and were located in the back of the rostel um and distributed around the scolex in the equidistance. When the scolex was in the motion states, the tegument muscular column on the rostel um contracted, the antler-like tooth-hook extended to periphery, and the sucker also made the ring-like and longitudinal-like contraction. [Conclusion] Ultrastructure of the scolex of C. pisiformis changed apparently during relative rest and motion states. Those changes help scolex to invade the host tissue.
